Crofter Posted November 20, 2014 Share Posted November 20, 2014 I have fitted a set of RDX LED indicators to my 1984 Land Rover 90, fitting was the easy bit, my problem is the wiring, when fitted and all wired up with good soldered connections all four flash together, I have a proper RDX flasher unit (it does not matter how this is adjusted the problem still exists) the dash warning light is also very faint, before this the trailer warning light used to flash occasionally with out a trailer, I don't know if this has any significance, also the old flasher unit was damp inside. Thanks in advance Ronnie. Quote Link to comment Share on other sites More sharing options...
JDexter Posted November 20, 2014 Share Posted November 20, 2014 From my limited knowledge of LED lamps you must use adhesive lined heat shrink to seal the joints between the loom and the lamp leads. There are special flasher units to be used with LED indicators as the lamps themselves draw much less current than a conventional incandescent bulbs.

Crofter Posted November 20, 2014 Author Share Posted November 20, 2014 Thanks JDexter, I have a proper flasher unit designed for the led indicators, I am interested in the adhesive lined heat shrink for the joint sealing I just used normal heat shrink, my son fitted the same to his 110, but its a lot newer so the plugs supplied were used a straight swap.

miketomcat Posted November 20, 2014 Share Posted November 20, 2014 Normal heat shrink is fine (mine are) I would suggest you have either a bad connection/earth or check your hazard switch as indicators go through it. Mike Quote Link to comment Share on other sites More sharing options...
Crofter Posted November 20, 2014 Author Share Posted November 20, 2014 Its a new hazard switch, so I am wondering if I upset something when I fitted this, the trouble with old vehicles is the state of the looms and connections. Quote Link to comment Share on other sites More sharing options...
eds Posted November 20, 2014 Share Posted November 20, 2014 I fitted these and had a problem The earths are crucial esp in the front wings.. The earths are used to make the telltale flash in the cluster. If your earths are not right it could be that voltage it triggering the opposite LEDs via the tell tale. Check your earths are perfect.

eds Posted November 20, 2014 Share Posted November 20, 2014 The flasher adjuster is only to stop the trailer flasher flashing when there is no trailer. I do not think it matters what kind of connecting you do, I just used bullets and insulation tape. Are you sure you wired up the indicators the right way round as both sides circuits are used when you indicate as I explained above. As LED's need so little current, any leakage could trigger both sides. Quote Link to comment Share on other sites More sharing options...
Early90 Posted November 20, 2014 Share Posted November 20, 2014 I had this happen when i fitted them to my 1984 90. Call the supplier and they will send you a led bulb for the dash, cured mine. Quote Link to comment Share on other sites More sharing options...
Crofter Posted November 20, 2014 Author Share Posted November 20, 2014 Early90, you say the same happened to you, did all four indicators flash at once? Quote Link to comment Share on other sites More sharing options...
Early90 Posted November 21, 2014 Share Posted November 21, 2014 yes, all was well, good earths with no previous problems other than dodgy bulb holders. Set the flasher relay as instructed and found all four flashing together when indicating left or right. I rang them, as i did not suspect a poor earth, and they were aware of the problem, they suggested i replace the dash indicator lamp with a led one. I was sceptical but it worked.

sean f Posted November 22, 2014 Share Posted November 22, 2014 I had this problem when fitting them to mine, there was a lot of swearing as I checked everything to find the problem. In the end I tracked it down to the dash indicator light, the origional wiring has the indicators for each side of the indicators wired to the sides of the dash light, so when you indicate left the power is supplied to the left indicators as expected and goes to earth through the bulbs to light the indicators, power is also feed to the left side of the dash light, this powers the dash light going to earth via THE RIGHT INDICATORS, with normal bulbs not enough power goes to the indicators for them to actually light so all is fine. With LED's because they need so little power the right indicators will light. I fixed it by wiring each side to a different dash light, bit of a bodgy but it works. A dash bulb with something different about it so less power is transmitted to the opposite side would also work I expect and this is probable what they supply. As a test remove the dash bulb and see if all the indicators work as expected, if they do this is a good place to start. Quote Link to comment Share on other sites More sharing options...
Crofter Posted November 23, 2014 Author Share Posted November 23, 2014 Thanks guys, I took the dash light out and the flashers worked, I would have taken ages to figure that out on my own. off to buy a led bulb, anyone know the type please.

Crofter Posted November 24, 2014 Author Share Posted November 24, 2014 I have ordered a LED bulb from Bolt on bits, it must be more than just a LED bulb, I think he said it had a earth, I thought of trying other fixes like two dash lights, but did not want a bodge, so I hope this works. My son fitted LED's to his 300 TDI 110 without all this trouble. Quote Link to comment Share on other sites More sharing options...
Simon Smith Posted November 26, 2014 Share Posted November 26, 2014 I disconnected the bulb and earthed one side of it, then fed the other terminal from the two original wires but with a diode in each. Quote Link to comment Share on other sites More sharing options...
Crofter Posted November 28, 2014 Author Share Posted November 28, 2014 Hi all, I took the easy way out and fitted a warning light from RDX, this has a separate earth and solved the issues I had. Thanks for the replies as It saved me a lot of time, I don't know how long it would have been before I figured it out on my own. It would be helpful if RDX mentioned this in their instructions or even supplied a light with the kit as it must be a common problem or they would not have warning lights on the shelf. 2 Quote Link to comment Share on other sites More sharing options...

Resurrection of an old topic I know, but I have just done the bolt on bits LED upgrade and have the same issue, as Crofter says it would be helpful if they put some info about this in the kit. I rang them and they said "oh yes we know all about it and sell a kit to fix it". However their kit is £15 (plus delivery no doubt) which I thought expensive for what is probably a bulb holder, an led bulb and two diodes. Shopping around revealed this on a motorcycle site http://matchlessclueless.com/store/led-indicators/led-indicator-diode/#tab-reviews Now ordered and I will review once fitted.

Crofter Posted December 4, 2016 Author Share Posted December 4, 2016 Hi , I would be very interested in this, do you just splice the wire with the diodes in and use the original bulb and holder? The Bolt on bits conversion works but it's very dim and in daylight it's hard to see, or at least mine is. Quote Link to comment Share on other sites More sharing options...
easytiger Posted April 16, 2017 Share Posted April 16, 2017 Update on this. The item took a while to arrive, I didn't realise that the motorcycle club concerned is not UK based! However when It did arrive it was simple to fit and has worked faultlessly since. While waiting for it to arrive I simply removed the bulb from the warning light. I am not sure what Bolt on bits provide but all that is required is a couple of diodes and some connectors so I have no idea how BOB justify the price.

I think that Bolt on Bits and other suppliers of the LED kits should really put something in the kit to explain the indicator problem instead of leaving their customers to reasearch themselves. (that's probably how they manage to get such a high price for their solution) Quote Link to comment Share on other sites More sharing options...
